A spectrophotometric and polarographic method is proposed for the determination of ruthenium tetroxide absorbed in oxalic acid. Spectrophotometric measurements of ruthenium in 1N oxalic acid were made at 375 m mu . In the concentration range from 2 to 36 mu g of rutherinm per ml the relative standard error amounted 14 to 1%, respectively. The polarographic determination was performed in a supporting electrolyte containing 1N oxalic acid and 0.006% thymol (as a maximum suppressor). Tbe determination is applicable in the concentration range from 4 to 120 mu g ruthenium per ml with a relative standard error of 15 to 0.7%, respectively. Hydrochloric sulfuric, and perchloric acid up to 0.5N does not interfer. In the presence of nitric acid spectrophotometric and polarographic determinations of ruthenium are impossible. (auth)
